Hi,
After the recent updates of qt5-qtwebengine there are white spaces in the
message window when using a Dark Theme.
Another user has just reported this on kde.bugs with a screen shot
https://bugs.kde.org/show_bug.cgi?id=379406
I don't know if it is a kmail or qtwebengine bug or even related to mesa/
nouveau saga.
Kmail 5.4.3
Plasma 5.9.5
Frameworks 5.33
Mesa-dri-drivers-13.0.4-3.fc25.nouvlock

It's a QtWebEngine regression. QupZilla also shows similar behavior, see
e.g. the start page, where only the rectangle in the top center is light
gray, the rest comes up white for me.

Thanks for the info/confirmation on which package has the problem Kevin.

Not sure if the new qt5-qtwebengine-5.9.0-2.fc26 in Koji has a fix for this,
but after testing it I find Kmail does not start so I had to roll back:
org.kde.pim.kontactinterface: "Cannot load library /usr/lib64/qt5/plugins/
kmailpart.so: (/lib64/libKF5MessageViewer.so.5: symbol free, version Qt_5 not
defined in file libQt5WebEngineCore.so.5 with link time reference)"
[1:1:0100/000000.289924:ERROR:broker_posix.cc(41)] Invalid node channel
message
KCrash: Application 'kontact' crashing..
Unable to start Dr. Konq
Does anyone else see this?

This sounds like:
https://bugreports.qt.io/browse/QTBUG-60565
but that is supposed to be already fixed in the 5.9.0 release that I
packaged. So this is very strange.
(By the way, Bodhi feedback and/or Bugzilla are better places to report such
showstoppers than a mailing list thread that I may or may not happen to read
in time.)

OK, I thought it was a good idea to check here before leaving neg karma incase
it was unique to my setup.
I see your working on a fix so I will hold fire leaving karma until I try the
new builds.

Just an update on this..
I have been testing F27 with the latest kde packages, frameworks 5.38,
applications 17.08.x (which had a shed load of fixes) especially in PIM and
the issue has gone now.
Maybe also related to QT as I see F27 runs qt-5.9.x now.
Slightly Off Topic,
I'm also testing Martins Plasma-5.10.95 (5.11 beta) which also is working
extremely well for me.
Thanks to everyone involved in providing the latest kde software group for
Fedora.

Thanks Colin,
I intended to update to F27, and PIM is a must for me. I have previously used
evolution and thunderbird and I have settled with kontact and associates, that is what
best
works for me. :-)

Yes The PIM suite is working very well for me José :-)
FYI, although I'm sure your aware,
Nouveau/Mesa have a very long standing problem, but thanks to Kevin he is
providing a patched Mesa so Kmail, QupZilla do not lock/crash.
https://bugzilla.redhat.com/show_bug.cgi?id=1376107
Sadly as recently commented in the bug report above, there are new upstream
issues with Nouveau and the system locking solid. I did start to see it in
F26.
A solution is I guess nVidia from RPMfusion but that is a last resort (for me)

You are right, answering with f27. :-)
There was an annoying bug in the previous version where a selection with multiple messages
that was moved to another mail folder would not be updated on the GUI.
Restarting akonadi would show the right behavior though. :-)

Hhahah - yes! This used to drive me frigging crazy... I'm so glad this got
fixed.
Now if only the crash on shuting down without exiting kmail would be fixed.
